GERMICIDAL COMPOSITION.

.No Drawing.

To all whom it may concern:

Be it known that I, FRED ANoEnsoN, a citizen of the United States,residing at Vallejo. California, have invented certain new and usefulImprovements in Germicidal Compositions, of which the following is aspecification.

This invention relates to a germicidal composition for external use andof powdered form, and is designed primarily for the killing of vermin ofthe parasitic class, but it is understood that a germicidal composition,in accordance with this invention, can be employed for any purpose forwhich it is found a plicable, and the invention has for its ob ect toprovide, in a manner as hereinafter set forth, a germicidal compositionwhich is thoroughly efiicient when applied for the killing of vermin andwithout injuring the surface to which it is applied, as well as having asoothing and counter-irritant effect on the surface to which thecomposition has been applied.

A germicidal composition, in accordance with this invention, is formedfrom a compound of creoline, water, alcohol solution of salicylic acid,alcohol solution of menthol, alcohol solution of camphor, sulphur andtalc powder.

The preferred proportions of the several ingredients of the compositionare as follows Creoline cc. Water 15 cc. Salicylic acid alch. sol. 21% 75 cc. Menthol alch. sol. 20% 50'cc. Camphor alch. sol. 20% 50 cc.Sulphur subl 100 gms. Talc powder 150 gms. Talc powder 1850 gms.

is incorporated in. the mixture 1850 gms.

of talc powder. I

A solution is first made of the creoline and water, in order to make thecreoline more mixable with the talc powder, and to Application filedFebruary 2, 1925. Serial .No. 6,467.

such solution is added the salicylic acid and the amount of water issuch that can be safely usedwithout precipitating the salicylic acidfrom the alcohol solution and such amount is 15 cc. The. alcoholsolution of menthol and camphor are readily mixable with the creolineand salicylic acid thus prepared and serve as soothing andcounter-irritant agents.

As the sulphur will not combine with the solution above formed from theconstituents set forth in the preceding paragraph, it has been foundnecessary to first mix it with a certain amount of talc and thenincorporate it with such solution, and therefore such mixture consistsof combining 100 gms. of sul hur with 150 gms. of talc powder.

Xfter the sulphur and talc powder have been added to the solution, thereis incorporated slowly in said mixture talc powder of an amount up totwo (2) kilos by weight, or 1850 gms. The object of incorporating thetalc powder slowly with the mixture is to get every microscopic crystalheld in the above solution evenly distributed throughout the bulk. Theamount of sali cylic acid' solution, as herein referred to, is 21%instead of 20% as about 1% is lost in the drying process.

After the ingredients have been combined, the bulk is dried, and thedrying should be done with utmost care while the bulk is constantlystirred. Too much heat applied The composition is to be kept in closedcontainers.

.It is thought that the many advantages of a germicidal composition, inaccordance with this invention, can be readily understood, and althoughthe'preferred embodiment of the composition is as described, yet it isto be understood that changes in the details of the proportions can behad which will fall within the scope of the invention as claimed.

What I claim is 1. A germicidal composition of powdered form consistingof a powdered mass of talc,

water solution of creolin, an alcoholic solution of salicylic acid, analcoholic solution of menthol and camphor, and a mixed body of talc andsulphur and with the talc of said body materially less in volume thanthe volume of the mass of talc.

2. A germicidal composition of powdered form consisting of 1850 grams ofpowdered tale, a .solution 'formed of 50 cc. of creolin and 50 cc. ofwater, 75 cc. of a 21% alcoholic solution oi salicylic acid, 50 cc. of a20% alcoholic solution of menthol, 55 cc. of an alcoholic solution ofcamphor, and a mixed body of 150 grams of talc and 100 grams of sulphur.

3. A method of manufacturing a germicidal composition of powdered formconsisting in combining a water solution of creolin with an alcoholicsolution of salicylic acid, menthol and camphor to rovide a liquid body,then combining with t e said liquid body a mixture of talc and sulphur,then incorporating slowly a mass of tale of a materially eater volumethan the volume of tale 0 said mixture into said liquid body to form amass, and then drying said mass while constantly stirring the same.

In testimony whereof, I aflix my signature hereto.

FRED ANDERSON.
